VENTILATOR Application led January 14, 1929. Serial' No. 332,403.

The present invention is directed to improvements in ventilators.

The primary object of the invention is to provide a device of this character more particularly designed for use in connection with railway coaches, but is not necessarily limited to such use.

Another object of the invention is to provide a device of this character so constructed that fresh air can be admitted to the interior of the coach or other closed vehicle,'provision being made to prevent cinders, dust. or other particles entering the interior of the coach with the incoming air.

Another vobject of the invention is to provide a device of this character constructed in such manner that the supply of fresh air can be conveniently regulated.

Another object of the invention is to provide a device of this kind which is simple in construction, durable, eiiicient in operation,

and one which can be manufactured at a small cost. v

With these and other objects in view, this invention resides in they novel features of construction, formation, combination and arrangement of parts 'to be hereinafter more .fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of a railway coach showing the ventilators in place there- Figure 2 is a fragmentary side view of the coach showing a ventilator in place upon the dome thereof.

Figure 3 is a plan view f an automobile, partly in section showing the adaptation of the invention thereto. j

Figure 4 is a sectional view on line 4--4 of Figure 1.

Figure Figure 4. l

The ventilator comprises a casing 1 preferably formed from sheet metal, said casing having a restricted central portion 2 into one side of which opens a collar 3, said collar being engagedin an opening 4 formed in the lower rail 5 of the coach window 6. The collar is spaced from the wall of the openin 50 4 to accommodate the rim 7 of the cap 8, said 5 is a sectional view on line 5-5 of rim having openings 9 formed therein and which are closed by screens 10. The top 11 of the cap 8 is provided with a handle 12 to facilitate adjustment ofthe cap.

Extending into the collar 3 are baffle plates 13-13 which have curved sections 14--14 suitably secured to the outer wall of the casing 1. These plates are spaced to accommodate the plate 15 therebetween, the outer end of said plate lhaving stops 16 carried thereby to limit the sliding movement thereof. The plate 15 is provided upon its inner end with a iange 17 adapted to be secured to the top 11 of the cap 8. The plates 13-13 define passages 18-18 in the collar which communicate with the primary air conducting passages 19-19 of the casing 1. The passages 19--19 are closed at their outer ends by screens 20, said passages having mounted intermediate their ends screens 21.

As indicated by the arrows in Figure 4, the air, when the coach is in motion, will be forced through the inlet end of one of the passages 19 and communicating passage 18 of the collar, and from thence into the interior of the coach. Obviously a slight suction will be created in the other passages 18 and 19. in

order that impure air will be drawn from the coach.

Since the passages 19 are independent the ventilators will efficiently function when the travel of the coach is reversed.

The supply of fresh air can 'be conveniently regulated upon adjusting the cap 8 upon the collar 3, and the supply can be wholly cut off upon entirely closing the cap.

' As shown in Figure 1, the ventilators are applied to the windows of a coach, but they may be placed upon other parts of the coach, as lillustrated in Figure 2, wherein a ventilator is shown applied to the dome of the coach.

In Figure 3, the ventilator 22 is shown applied to the top of a motor vehicle, the construction thereof being substantially the same as that of the form applied to a coach with the exception of a slight difference in shape, and since the operation is the same a detailed description thereof is not thought necessary.

A ventilator constructed in accordance with the invention may be readily placed upon various types of vehicles and constructed in such manner that fresh air can be directed to the interior of the vehicle without creating a draft'. s From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in -the art, without further description, and it will be understood that various changes in the size, shape, and proportion and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention. What is claimed is '1. A ventilator comprising a casing having a collar opening into one side thereof, 'baille plates fixed transversely of the casing and ex tending into the collar to provide independent air passages leading from the end of the casing into the collar, and a cap adjustably mounted upon the c ollar and having a plate carried thereby for slidable engagement between the baile plates, as and for the purpose 2s set forth.

2. A ventilator comprising a casingha a collar communicating with the interior the casing intermediate its ends, bailie plates fixed transversely of the casing and extending into the collar to provide inde endent air conducting passages, a cap adjustably mounted upon thecollar and having screened openings therein to permit e ess of air from the passages, and a late ed to the cap and slidably associate 3. A ventilator comprising a casing having -a restricted central portion, a collar opening intoone side of said portion, balile plates fixed transversely of the casin f and extending into the collar and dividing t e casing and collar into independent air conducting passages, a cap adjustably mounted on the collar and having screened openings communicating with-the passages in the collar, and a late red in the cap and siidable between the aille p ates. k l 4. A ventilator comprising a casing ha a collar opening thereinto, baiile plates fix transversely of the casing and extending into 4 the collar and providing independent air pas sages in the collar and casin a cap Slidably adJustable on the collar and openings coinciding with the assages, a plate movable with the cap'and sli ably associated 55. with the balile plates, screens closing the ends of the casing, and screens mounted in the passages between the end closing screens and aliie plates.

dow having an opening therein, of a ca sing having a collar opening into the central portion thereof, said collar being adapted to engage in said opening, baiile plates fixed .6 transversely in the casing and ,extending into the collar, a cap sldably adjustable on the aving screened v 5. The combination-with the rail of a win-A anda collar and movable in the opening) etween plate fixed to the cap and slidable thev baie plates. v

6. A ventilator comprising an open-ended casing having a collar opening into one side thereof, baffle plates mounted in the casing and extending into the collar to form independent air passages leading from the open ends of the casing into the collar, a closure cap slidably mounted upon the collar for controlling the egress of air from the passages, and means carried by the cap and cooperating with the baille plates to prevent withdrawal ofthe cap from the collar.

In testlmony whereof we aix our signatures.
